Hardware Reset to Change BIOS password
The one of the good and dirty way to reset BIOS password is hardware reset. To do this you need to open the Computer cabinet and remove the CMOS battery on the mother board. After removing the battery wait one minute and insert the battery back. The BIOS information is stored in CMOS memory and when the power to CMOS disconnect the stored information will be erased. So nest time when the system boots BIOS will not ask you for password to grant access in to BIOS settings page.

A. By Using the Motherboard Jumper:
In most motherboards CMOS battery is soldered, which makes it difficult to remove the battery. In this case we use another method.
Almost all motherboards contain a jumper that can clear all CMOS settings along with the BIOS password. The location of this jumper varies depending upon the motherboard brand. You should read your motherboard manual to check its location. If you don't have the manual then look for the jumpers near the CMOS battery. Most of the manufacturer label the jumper as CLR, CLEAR, CLEAR CMOS, etc.
When you find the jumper, look carefully. There will be 3 pins and the jumper will be joining the center pin to either left or right pin. What you need to do, is remove the jumper and join the center pin to the opposite pin. e.g. if the jumper joins center pin to left pin, then remove it and join center pin to right pin. Now wait for a few seconds and then again remove the jumper and join the center pin to left pin.
Make sure to turn the PC off before opening the cabinet and resetting the jumper.
